A Pt-catalyzed, highly regioselective, reaction between N-allenamides and imino-alkynes leading to pyrrolo[1,2-a]indoles is described. This represents the firstexample of [3+2]-annulation of Pt-bound azomethine ylides with the distal C=C bond...
A norbornene-mediated palladium-catalyzed tandem alkylation/cyanation sequence is described in which an alkyl-aryl bond and a nitrile-aryl bond are formed in one pot. A variety of sterically hindered, five-, six-, and seven-membered ring benzonitriles were synthesized in good yields from easily accessible starting materials.
